8 Claims. (Cl. 'I2-44) The invention relates to a ,double glass wall or partition construction' having for its principal objects the provision of an improved wall structure having good heat insulating and light transmitting characteristics, which can be made cheaply to ll any desired space, which is relatively strong and light and which can be prefabricated and then installed or can be fabricated on the job. Certain embodiments of the invention are illustrated in the accompanying drawings, where- Figure 1 is a. perspective sectional view illustrating the construction. Fig.. 2 isa perspective view showing a part of the cellular frame structure. Fig. 3 is a partial section on the line III-III of Fig. 1. Fig. 4 is a partial section on the line IV-IV of Fig. 1. Fig. 5 is a sectional View taken at the edge of the frame. Fig. 6 is a section through a modified form of inner frame strip. Fig. 7 is a perspective View illustrating a 'modification Figs. 8 and 9 illustrate a modified means for attaching the glass strips to the cellular frame, Fig. 8 being a sectionl and Fig. 9 a face view of the construction. Fig. 10 is a section view showing amodification. And Figs. 11; 12., 13 and 14 illustrate additional modifications.

Referring first to the construction illustrated in Figs. 1 to 5, the numeral I5 indicates a brick wall, in which the construction constituting the invention is mounted, and I6 is an outer frame, in the present instance of wood, which is secured in the opening in the brick wall and constitutes the boundary of the inner cellular frame, in which the glass plates forming the faces of v the installation are supported. The inside sectional frame is made up of the series of vertical strips I1, I1, Il, etc. and a series of horizontal strips I8, I8, I 8, etc., the spacing of the sets of strips being preferably such that the cells formed are rectangular and of the same size. The strips I1 and I8 are notched, however, where they cross, as indicated at I9 and 20 so that when fitted together, a cellular frame is formed somewhat similar to that employed in egg crates. The cellular frame is secured in the outside frame I6 by means of the nails 2| (Fig. 5) or other suitable securing means.

As indicated in Fig. 3, each of the strips I'I and I8 is preferably made upof 'the two layers 2Ia, 2Ia which may be secured together by cementing or by suitable vrivets 22. The purpose of this two-layer construction is to provide for the reception of the metal strips I9a whose outer edges are formed into the circular beads a for securing the glass sheets in position. The material of the strips I'l and I8 is preferably fiber board having a tensile strength of about 5,000 lbs. per square inch, although laminated wood or ,other'suitable organic material which is relatively strong and tough might be employed. Such materials are preferred, as compared with metal because of their cost, and because the danger of glass breakage is less in a support of this kind than in a metal support, a metal framing being subject to a relatively high degree of expansion and contraction under changing heat conditions, so that precautions have to be taken as to clearance which are not required with a frame of fiber board and the like.

Each of the cells formed by the inner frame is covered on its two sides by the glass sheets 23 and 24 which are preferably square and have their edges beveled so as to receive the cylindrical heads 20a of the holding strip I9. The holding strips Illa are required only ontwo edges of each plate, as indicated in Fig. 1, and after the assembly is made, the cylindrical heads 20 are collapsed by any suitable means, such as the tool 24a provided with a roller 25 as shown in Fig. 3, the right hand side of this ligure showing the cylinder or beadin collapsed position. After the hollow beads are collapsed, the space outward therefrom is preferably filled with a plastic caulking material 26 which forms a seal and assists in securing the glass plates in position. A wide variety of glass plates may be used. They may be of rough rolled sheet glass having any desired conguration, or they may consist of plates which are pressed to the desired shape. Colored glass may also be used on one or both sides of the frame in order to secure ornamental elects.

If desired, the strips Il and I8 may be made of onethickness 21, as indicated in Fig. 6, the edge strips being secured in position by means of rivets 28. At the edges of the glass plates which are not held by the securing members I 9c, the spaces between the beveled edges of the plates are merely filled with caulking material 29, as indicated in Fig. 4.

In the modication shown in Fig. '7, the holding strips IS having the heads 20a are employed on all four sidesof the vglass plates, the construction in other respects being the same as heretofore described. This gives some additional security in holding the glass plates, but is not ordinarily required.

Figs. 8 and 9 show another -method of securing the glass plates 23 in position on the inner frame. In this case, the strips 30 constituting the frame are in one layer and the wedge-shaped recesses between the edges of the plates carry metal strips 3i which are perforated for the passage of the `spaced screws 32 which extend into the fiber board strips 30.

In the construction shown in Fig. 10, the glass plates 23 are secured to the strips 33 constituting the cellular frame by means of the strips 34 held in position by means of the rivets 35. The outer ends of these' strips 34 are bent over the faces of the glass sheets, as indicated at 36, and in this case, no beveling of the glass sheets isrequired.

Figs. 11 and 12 illustrate another modification, in which one set of strips constituting the inner frame, such as the vertical strips 31 are made continuous instead of being notched at their edges as is the case in the Fig. 1 construction. The strips running transversely of the strip 31 are made in sections, such as the section 38 and are provided at each end with a dowel 39 which fits into a dowel recess 40 in the strip 31. As in the construction of Fig. 1, the strips are made in four times that of the upright members l1 of the Fig. -1 construction. As a whole, therefore, this construction of Figs. 11 and 12' is nearly twice as strong as that of the construction o`f Eig. 1. On

the other hand, it is more expensive to construct and install. y

The construction of Fig. 13 is on the order lof l -that of Figs. 11 and 12 except that the sheet sections 41 are secured to the through sections 42 by means of angle strips 43.

Fig. 14.- illustrates the use of avlmetal inner frame, in which the two sets of strips 44 and 45 are of shell-like form and may be made of thin copper, aluminum or other rolled sheet metal. These strips may'be` soldered together at their intersections and are provided with beads 46 corresponding in function to the beads a of the construction heretofore described. The installation and securing of the glass is the same as heretofore set forth, the beads beingV pressed down after the glass plates are installed and the caulking material applied to cover the collapsed edges. forcing filler of wood or the like.
